The One Laptop Per Child Project and Microsoft are working together to develop a dual-boot system to put both Linux and Windows on laptops aimed at kids in developing countries, the head of OLPC said in an interview Tuesday. "We are working with them very closely to make a dual-boot system so that, like on an Apple, you can boot either one up. The version that's up and running of Windows on the XO is very fast, it's very, very successful. We're working very hard to do both," said Nicholas Negroponte, chairman of OLPC.
